More specifically, it relatesto gasoline pumps.

A principal object of the present invention is to provide a portablepump that can be conveniently carried in a car so to be handy for use incase the car runs out of gas on a highway far from a gas station; thepump allowing the motorist to transfer some gas from another vehicleinto his own car so that the car can resume travel in order to get to agas station for then being fully refuelled.

Another object is to provide a portable pump that can be effortlesslyoperated by electric power from a cigarette lighter of the vehicle, thuspreventing the need to syphon the gas by placing the hose in a personsmouth and sucking on it, which practice is dangerous due to lead andother harmful ingredients being in the gas.

Yet another object is to provide a pump that can be supported by apermanent magnet to a side of the vehicle where it is convenient tocontrol, instead of placing down upon a ground.

Other objects are to provide a centrifical syphoning pump which issimple in design, inexpensive to manufacture, rugged in construction,easy to use, and efficient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing, wherein:

FIG. I is a side view of the invention shown in operative use.

FIG. 2 is an end view of the pump unit supported by a magnet to a bodyof the car.

FIG. 3 is a cross section on line 33 of FIG. 2.

FIG. 4 is a side view of a modified design of the invention.

FIG. 5 is a cross section on line 5-5 of FIG. 4.

FIG. 6 is a cross section of still another form of the invention.

Referring now to the drawing in detail, and more particularly to FIGS. 1to 3 at this time, the reference numeral 10 relates to a centrificalsyphoning pump that includes a unit 11 having a case 12 with a chamber13, in which there is an electric motor 14 of six or twelve volt type soto be powered by a battery of a car. An extension cord 15 from the motoris attached to a plug 16 that is designed so to fit into a cigarettelighter outlet 17 of a car 18. The extension cord 15 is forked so toinclude a plug 19 with prongs 20 receivable in a 110 Volt A.C. householdelectric outlet socket, in which case the plug can include a transformer21 to step down the voltage for the motor, so that either power sourcecan drive the motor. A switch 22 is on the case.

A motor shaft 23 extends into a pump chamber 24 having inlet port 25 andoutlet port 26; the shaft having impeller 27 mounted on it. A hose 28 isconnected to the inlet port, and a hose 29 is connected to the outletport.

In use, when a car 18 runs out of gas along a road, the hose 29 isinserted into the gas tank filler pipe 30, while the hose 28 is inserteddown into the gas tank 31 of any stopped, assisting automobile 32 thathas gas. The case 12 has a permanent magnet 33 on its rear side so thatit can be held to any steel surface of a car in order to be convenientfor operation. A soft thin felt pad 34 on the surface of the magnet willprevent the magnet to 2 scratch any car body finish. The plug 16 isinserted into the cigarette lighter outlet and the switch 22 is turnedon. Thus, enough gas is put into the empty car tank so it can resumetravel.

In FIGS. 4 and 5, a modified design of pump 35 is shown which has theadvantage of no moving machinism within the stream of the gasoline sothat the pump can be marketed without the necessary U.L. approvalrequirements. I

The pump 35 simply comprises a squeezable hose unit 36 extending betweenthe gas tanks of the two vehicles, and the hose portion between the carsextends uninterrupted through a unit 37 having a motor driven wheel 38that carries elliptical rollers 39 that squeeze the hose so to urge themovement of gasoline through it. The rollers are retractable along wheelspokes 40 against springs 41 so that the rollers travel for a distancealong the hose. A pull from a spring 42 can be included so that the hoseimmediately restores rounded out after a roller passes so that lowerpressure develops in order that pumping action from the supply tank isobtained. One-way flap valves 43 and 44 could be located in oppositeends of the hose. The elliptical rollers give pulsation to the flow.

In FIG. 6, another design of pump 45 would be hand operated by includingan axially compressible accordian section 46 connected between hosesections 47 and 48. Flap valves 43 and 44 would be included. Simplysqueezing the knurled handles 49 and 50 toward and away from each othercauses pumping action, without need of any electric motor.

Thus different forms of the invention are provided.

I claim:

1. In a pump for syphoning gasoline from a tank of one automobile to atank of another automobile, the combination of hose means, each endbeing inserted into one said tank, said hose means communicating with apump unit located along said hose means, said pump unit including a casewith a permanent magnet on one side for holding to a steel body of onesaid automobile, said case containing an electric motor that is poweredfrom a cigarette lighter outlet of said automobile, said motor driving agasoline pump, and one way flap valves along said hose means, beinglocated on each side of said pump so to prevent return flow.

2. The combination as set forth in claim 1, wherein said hose meanscomprises a single hose extending straight through said case, said pumpcomprising a plurality of radially extending spokes secured to a shaftof said motor, each spoke slidably supporting an L-shaped holderslidable against a compression spring around said spoke, and each holdersupporting a freely rotatable elliptical roller rollable along a surfaceof said hose so to squeeze said hose and force a pulsed flow of gasolinetherethrough.
